Answer:
yes
Explanation:
because the strong winds and the weight and there are more things to break
Explanation:
A tall tree may have more resistance to the wind since it has more mass ( branches, leaves). That means the wind has more mass to push against. Winds may also be stronger at a higher level. Tall trees have been growing longer and have more chances to have been compromised by insects, animals, fungi and so on. They also have less flexibility since they need to be more rigid to hold up the mass of branches they have.
1000 mm =
covert the following into metres with working
Answer:
1m
Explanation:
The conversion is 1mm = 0.001m. So all we need to do to find how many mm there are in a meter, all we need to do is divide by a 1000;
1000 / 1000 = 1m
Best of Luck!

1+
5+
1–
5-
Answer:
1–
Explanation:
The fluorine is the element with biggest electronegativity in the periodic table, so it usually always take an electron and gets charge 1–
The valence electrons that Fluorine possesses is 7. Then, the charge of its ion would most probably be:
C). 1–
Fluorine is the element having F as its symbol and 9 as its atomic number(9 protons).
As we know, valence electrons are the electrons that are available in the surface shell of the atom. This is the reason that such electrons can make bonding with some other atoms as well. Since Fluorine contains 7 valence electrons, it would have a charge of 1– because it will acquire extra electrons to form the bond. Fluorine's valence shell would contain [tex]2s^{2} 2P^{5}[/tex] i.e. 7 valence electrons.Thus, Fluorine is the chemical element that possesses the highest electronegativity i.e. of around 3.98.Learn more about 'chemical elements' here:

Frictional force is produced when two different objects are in very close contact and are slided against each other.
It also depends on the roughness of the object i.e, the rougher will be the object the higher friction will be produced and vice-versa.

pls guys i have a serious question thats in my brain for a long time.
Find the highest acceleration
best answer = brainlist
The greatest acceleration on the graph is 4 m/s² .
"Acceleration" means how fast velocity is changing.
Changing velocity means changing speed OR direction.
This graph doesn't tell us anything about the direction of motion, so we can only work with speed.
The "greatest" acceleration means the biggest change of speed in the shortest time.
Your picture of the graph is pretty fuzzy, and I'm not sure I can actually read everything correctly.
The y-axis looks like it's velocity, and I THINK the numbers are 0, 20, 40, and 60, in meters per second.
The x-axis looks like time, and I THINK it's marked 0, 10, 20, 30, 40, 50, 60, 70, and 80, in seconds.
Now, each straight piece on the graph shows a change of velocity and a change of time. So the SLOPE of each piece is the acceleration of that piece.
==> On the first piece, from 0 to A, the velocity changes from 0 to 20 m/s, and the time changes from 0 to 20 sec. The slope of that piece is (20 m/s) / (20 sec), so the acceleration is 1 m/s² .
==> On the level piece from A to B, the velocity is 20 m/s. It doesn't change, from 20 to 30 sec. It has no slope, so the acceleration is zero.
==> On the piece from B to C, the velocity rises (60 - 20) = 40 m/s, and the time changes (40 - 30) = 10 sec. The slope is (40 m/s) / (10 sec), so the cceleration on that piece is 4 m/s² .
==> Finally, on the last piece, from C to D, the velocity DROPS from 60 to 0 m/s, during the time from 40 to 80 sec. The change in velocity is -60 m/s, and the change in time is 40 sec. So the slope of the piece, and the acceleration, is (-60 m/s) / (40 sec) = -1.5 m/s² .
The greatest acceleration shown on the graph happens along the line segment from B to C, from 30 to 40 seconds. During that time, the velocity changes from 20 to 60 m/s. That's an acceleration of 4 m/s² .

An experiment is conducted to determine how the arm length of a pendulum affects its period. The experimental design calls for varying the length of the arm and the mass of the bob.
Which is true about this experiment, based on good experimental design?
Only the arm length should be changed. The mass should remain the same.
Only the mass should be changed. The arm length should remain the same.
The force applied to the mass should be varied for each trial.
The material the arm is made of should be varied for each trial.
Answer:
Option (I)
Explanation:
The independent varible is arm length. Therefore, to eliminate the effect of other factors and make a valid and effective conclusion, only the arm length should be changed, while other factors (mass, force and materials) should remains the same.
Answer: Only the arm length should be changed. The mass should remain the same.

State Archimedes principle
[tex]\huge\bigstar{\underline{{\red{A}{\pink{n}{\color{blue}{s}{\color{gold}{w}{\color{aqua}{e}{\color{lime}{r}}}}}}}}}\huge\bigstar[/tex]
Archimedes’ principle is the physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body. The volume of displaced fluid is equivalent to the volume of an object fully immersed in a fluid or to that fraction of the volume below the surface for an object partially submerged in a liquid. The weight of the displaced portion of the fluid is equivalent to the magnitude of the buoyant force. The buoyant force on a body floating in a liquid or gas is also equivalent in magnitude to the weight of the floating object and is opposite in direction; the object neither rises nor sinks. For example, a ship that is launched sinks into the ocean until the weight of the water it displaces is just equal to its own weight. As the ship is loaded, it sinks deeper, displacing more water, and so the magnitude of the buoyant force continuously matches the weight of the ship and its cargo.
Answer:
Archimedes principle states that"When a body is fully or partially immersed in a liquid,it experience an upthrust which is equal to the weight of the liquid displaced"

Which diagram shows the effect of cutting the
acceleration in Part A in half and not changing
the value of the initial velocity?
Acceleration is the rate of change of velocity over time. The diagram that shows the effect of cutting acceleration by half without changing initial velocity is graph (c)
The equation is given as:
[tex]v = 2t + 4[/tex]
The first equation of motion is:
[tex]v = u + at[/tex]
By comparing both equations, we have:
[tex]u = 4[/tex] --- initial velocity
[tex]a = 2[/tex] --- acceleration
When the acceleration is cut in half, the new acceleration is:
[tex]a_{new} = \frac a2[/tex]
[tex]a_{new} = \frac 22[/tex]
[tex]a_{new} = 1[/tex]
So, the equation of velocity is:
[tex]v = u + at[/tex]
[tex]v = 4 + 1 \times t[/tex]
[tex]v = 4 + t[/tex]
When [tex]t = 0[/tex]
[tex]v = 4 + 0 = 4[/tex]
When [tex]t = 1[/tex]
[tex]v = 4 + 1 = 5[/tex]
The graph of velocity that satisfies [tex]v = 4 + t[/tex] and the values of time (t) and velocity (v) tested above is (c).

How do data collected from tree rings provide evidence for climate
change?
Why isn’t this a answer when you search it
Answer:
Climate scientists compare the tree growth records to local weather records. For locations where a good statistical match exists between tree growth and temperature or precipitation during the period of overlap, the ring widths can be used to estimate past temperature or precipitation over the lifetime of the tree.
